ATHLETIC SHOE .Filed May 25, 1931 Patented 9, 1934v UNITED STATES PAT-ENT oer-'ics 1,942,574 ATHLETIC SHOE Application May 23, 1931. Serial No. 539,554 2 Claims. (Cl. 36.59)

My invention relates broadly to athletic shoes of a type carrying cleats or treads on the sole and heel thereof and, while applicable to various types of shoes used for various sports, such as 5 golf, running, etc., is especially adapted for football shoes.

-A particular object of my invention is to provide a new and improved cleat which will be readily removable and replaceable on a shoe and lo which will be securely mounted thereon and clamped to the sole thereof in such a manner that, should the cleat by any mischance be broken off, the securing means cannot possibly be forced upwardly into the shoe, to the possible injury of the wearer.

A special object of my invention is to provide a cleatl of the type referred to which will comprise a securing member clampable to a shoe 501e,

which member will always have a portion of a predetermined xed length projecting from the bottom of the sole for the attachment of the tread. f

Still another object is to provide such a device which will be simple in construction, inexpensive to fabricate, efilcient, and rugged.

Various other objects and advantages will become apparent as the description proceeds.

Referring now to the drawing forming part of this specification and illustrating certain preferred embodiments of my invention:-

Fig. 1 is a fragmentary longitudinal sectional view through a shoe embodying my invention;

Fig. 2 is a perspective view of the attaching means of the embodiment shown in Figure l. the parts being shown in spaced relation for clearness, and

Fig. 3 shows an elevation and a top plan view of a modified form of one of the elements of my attaching means.

In Figure 1 the numeral 10 represents a shoe comprising an upper 11, an insole 12, and a sole 13. The sole 13 may be formed of one piece of leather as shown, or may be built up of several plies as is common in the art.

Applied to the sole of the shoe are a number of cleats. indicated generally at 15. spaced as desired, and it will of course be understood that similar cleats may also be arranged on the heel of the shoe. These cleats are attached to the shoe by means of tubular studs 16 which extend through the sole, each stud being threaded on the interior thereof and having an enlarged head 17. A plurality of ears or webs 18 extend between the head 17 and the tubular portion, these webs having relatively sharp edges for the purpose of bitingv into the Ileather and preventing rotation of the stud relative to the sole. The sole is, of course, apertured to receive the studs 16 and, while in the embodiment shown the head 17 of the stud preferably rests flush with the top-of the 30 insole l2, it willbe readily understood that. if desired, the head may be flush with the top of the sole 13 and the insole 12 may lie above the studs. Co-operating with veach tubular stud 16 is a stud member 20. This member comprises a 55 screw portion 2l which threadedly engages the female threads of the tubular stud 18 and a screw portion 22, an enlarged member 23 being formed integrally with the member 20 between the screw portions 21 and 22. As shown in Fig- 70 ure 2, the portion 23 is preferably polygonal in shape to facilitate engagement thereof with a tool for screwing it intov engagement with the member 16. It also functions to clamp the stud 16 to the sole of the shoe. A washer 24 is pref- 75 erablyarranged on the screw portion 21 and normally engages the bottom of the shoe sole. serving as a base for the cleat to prevent distortion thereof.

Threadedly engaging the stud portion 22 is a 30 nut or like threaded member 25 which is preferably molded into the tread member 26, 'the latter being preferablyformed of rubber or other suitable plastic material. As clearly shown in Figure 1, the tread member 26 lis preferably 35 frusto-conical in shape and is formed with a substantially axial bore 27 registering with the nut -25 and with an enlarged cylindrical space 28 at the uppel` portion of the tread.

The assembly of the parts is thought to be obvious. The tubular stud 16 is inserted through its aperture in the shoe, sole in the position shown in Figure 1. The stud member 20 is then threaded into the tubular stud 16. with the washer 24 in place as shown, so as to clamp the tubular stud 16 securely tothe sole. It will be noted 1 from Figure 1 that the tubular stud 16 is preferably slightly shorter than the thickness of the sole. This is for the purpose of cushioning the stud member 20 and washer 24, whereby a tight clamping engagement is effected. 'I'he tread v member 26 is then screwed into tight engagement with the washer 24 by means of its embedded hut 25. the cavity 28 serving to house the enlarged portion 23 of the stud member 20.

It will be noted that by means of my construction, after the assembly of the stud member 20 with the tubular stud 16, a fixed length of screw 22 protrudes from the bottom of the shoe in all cases. regardless of any variation in the thickness llo eel of the sole. This is of value in that the tread member 2d will always be secured to the stud 22 of the tread member 26 be torn from the member 25 in use, it vwill be practically impossible for the wearer to injure his foot by forcing any of the securing means up through the sole of the shoe, inasmuch as the enlarged member 23 and washer 24 will effectively block any such up' ward movement. The stud member 20 is also readily replaceable, should it fail for any reason. It will also be noted that the screw portion 22 of the stud 20 is smaller in diameter than the portion 21, so that any failure which might occur in the stud will be below the enlarged portion 23: hence, this portion will remain and removal of the portion 21 may thus be easily removed by a tool.

It will also be apparent that the tread member 26 may readily be replaced, .should it become worn or broken in the course oi wear. Hence,

1 the device is extremely economical for the user.

Referring tol Figure 3, there is shown here a tubular stud representing'a'modincation o! the stud 16 shown in Figure 1 and comprising a tubular interiorly threaded portion 30 having a head 3l. The head 31 may be substantially flat and a plurality of tangs 32 may be struck downwardly from adjacent the periphery thereof for biting into the sole and thus effectively preventing rotation of the cleat relative to the sole.

Various other modifications, variations and.

improvements coming within th` spirit of my invention will. doubtless occur to those skilled in' the art. Hence, I do not wish to be limited to the precise forms shown or uses mentioned except as set forth in the appendedclaims, which Leaders enlarged cavity adjacent the upper portion there-A of communicating with said bore, a Washer disposed between said tread member and said sole,

and an integral member uniting said tread with saidinteriorly threaded member, said uniting member comprising a screw portion* engageable with the threads of said tread member, a. screw portion engageable with said interiorly threaded member, and an enlarged portion disposed between said screw portions for clamping said interiorlythreaded member to said sole, said enlarged portion being housed in the enlarged cavity of said tread member.

2. In a device of the class described, a shoe having an apertured sole, an interiorly-threaded stud member extending therethrough and having an enlarged head, a tread member formed of plastic material and having an interiorly threaded securing member molded therein and also having an axial bore registering with said securing member, and an integral member uniting said tread member with said stud member, said uniting member'comprising a screw portion engageable with the threads of saidv securing member, a screw portion engageable with said stud member, and an enlarged portion for clamping said stud member to said sole, said uniting member being normally engageable ywith said stud member to clamp the latter to .said sole prior to the attachment of the tread member. v
